Title 17, Section 93106 (b)(2) states: Any person who sells, supplies, or
offers for sale serpentine material in California shall provide with each sale or supply a written receipt containing
the following statement:

"Serpentine material may have an asbestos content greater than five
percent (5.0%). It is unlawful to use serpentine material for surfacing unless the material has been tested and
found to contain less than or equal to five percent (5.0%) asbestos. All tests for asbestos content must use California
Air Resources Board Test Method 435, and a written record documenting the test results must be retained for at
least seven years if the material is used for surfacing."

You must have this statement on your receipt whether the serpentine material
will be used for surfacing or not. Additional restrictions apply.

Any material containing 10% serpentine as determined by a registered geologist
is considered "serpentine material".

$10,000 for each day of violation could be assessed.

If you sell, supply, or offer for sale serpentine material, make sure that
